While the … 4/20 converted into a fraction WebMammalian DNA methylation patterns vary in time and space. In human somatic cells, m 5 C accounts for ∼1% of total DNA bases and therefore affects 70%–80% of all CpG dinucleotides in the genome ( Ehrlich 1982 ). This average pattern conceals intriguing temporal and spatial variation.

WebAlpha satellite DNA, also known as alphoid DNA is the centromeric DNA repeats/units in human centromeres. Although the sequence of regional centromeres contributes to the centromere function, it is not definitive.
